Pica, or the ingestion of non-food items, is found in species as varied as parrots, humans, and domestic cats. It’s unclear why some animals eat things that aren’t food – some guesses include stress and nutritional deficiencies. This behavior in cats was first noticed in Siamese cats, who are prone to sucking and eating woolen items. However, once all breeds (including the domestic shorthair) were included in studies, it became apparent that this behavior isn’t limited to the meezers in any way.

A new study, Characterization of pica and chewing behaviors in privately owned cats: a case control study, sought to better understand factors that might predict pica in cats, in the hopes of helping the veterinary community in developing effective treatments. This study surveyed 91 pet owners with cats who ingested non-foods, and included a control group of 35 cats who did not.

The researchers asked questions about basic kitty demographics, including age, breed, sex, medical history. They also included questions about the environment (including types of enrichment available, other people and animals in the house, and access to the outdoors). Finally, they asked questions about potential gastrointestinal signs, such as vomiting and diarrhea.

All cats in the pica group ingested non-food items, with 79 of them also chewing (but not swallowing) other things on a regular basis. Twenty one out of thirty-five of the control cats (that’s 60%) also chewed on things that aren’t really chewables!

What do cats with pica like to “eat?” Perhaps not surprisingly, shoelaces, plastic, and fabrics were all in the top three. Other interesting choices included toilet paper, soap, ear plugs, kitty litter, and sponges. Plastic, paper, rubber, and wood were the chew-toys of choice for the cats who were chewing on items.

A new study looks at pica and chewing behavior in cats.

Does your cat like to chew on things that aren’t food? If so, you are not alone. I personally have had cats who liked to chew paper (one cat shredded my rent check once), cardboard, corners of the carpeted cat tree, and the ever-popular plastic bag. Have you ever wondered WHY your cat does this?

When an animal ingests non-food items, that behavior is called pica. Humans do it too, with the most common targets being dirt or paint (yum!). The cause is not well-understood, with nutritional deficiencies, parasites, need for fiber, and obsessive-compulsive disorders all being tossed into the ring of possible reasons.

A new study, “Characterization of pica and chewing behaviors in privately-owned cats: A case-control study,” tried to get a handle on some of the factors that characterize pica in housecats. Previous research has suggested an influence of breed on the ingestion of fabric, with oriental cat breeds showing a predilection toward fabric-chewing and ingestion. Others have suggested that being housed indoors only is a factor, pointing to boredom and stress as a possible cause.
